TV Home Screen Icon List for Content Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital home appliances, such as devices for playing electronic content, often require multiple users to interact with a limited control panel and display, making it difficult to provide favorable visibility and simplicity of operation, especially when using a television screen.
Innovation Solution
An information processing apparatus and method that generates a selection screen with a list of icons representing various items of content, including a search icon, to facilitate user selection and navigation, particularly designed for use on a television screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a control panel with fewer buttons and smaller display area is used, then device complexity is reduced, but ease of operation deteriorates due to poor visibility and difficulty in detail operation
Solution Approach 1:
The control panel is segmented into multiple functional areas: a directional operation area with larger buttons for navigation, a confirmation area with prominent buttons for selection, and a display area that shows both operational status and detailed information. This segmentation allows each area to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The display area utilizes vertical space by arranging icons and information in multiple rows, allowing detailed content to be displayed without increasing the horizontal footprint. The directional buttons are arranged in a cross pattern that utilizes both horizontal and vertical dimensions for navigation control.
2Illumination intensity
If a television screen is used for display, then visibility from a distance is improved, but ease of operation deteriorates due to large size and difficulty in precise input
Solution Approach 1:
Different regions of the control panel have different characteristics: the directional buttons are positioned for easy access with larger hit areas, the confirmation buttons are prominently displayed, and the display area provides both overview and detailed information. This local differentiation optimizes both visibility and operability for television screen usage.
3Adaptability or versatility
If multiple users interact with a limited control panel simultaneously, then adaptability is improved, but ease of operation deteriorates due to shared access constraints
Solution Approach 1:
The control panel is designed with universal functionality where the directional buttons can be operated by any user for navigation, and the confirmation buttons can be pressed by any user for selection. The display shows information that is relevant to all users, enabling multiple users to interact with the system simultaneously without requiring user-specific controls.

AI summary
A screen generating unit generates a home screen for allowing a user to select a desired item of content from among multiple items of content, and the home screen includes a list in which multiple icons representing the multiple items of content are arranged. A display control unit displays the home screen on a television monitor. The screen generating unit further arranges, in the list on the home screen, a library icon used to search for an item of content.
